BACKGROUND OF THE INVENTION
The present invention relates to a storage buffer member and a transport box for storing a plastic container storing a glass substrate, a photomask blank, a reticle for manufacturing a semiconductor integrated circuit, a photomask, and the like.
[0002]
[Prior art]
A reticle or photomask used when transferring a fine pattern to a semiconductor wafer in the manufacture of semiconductor chips such as semiconductor elements, ICs, LSIs, etc. is obtained by sequentially laminating a light-shielding layer and a resist on the surface of a transparent glass substrate. It is created by patterning the light shielding layer into a predetermined shape and stripping the resist. Here, the substrate in which the light shielding layer and the resist are sequentially laminated on the surface of the transparent glass substrate is generally referred to as photomask blanks.
When transporting these glass substrates, photomask blanks, reticles, photomasks, etc., after storing a plurality of them in a plastic container, store the plastic container in an outer box made of cardboard or the like and transport the entire outer box. Is generally done.
[0003]
However, if the outer box is accidentally dropped during transportation, or if the handling is rough when loading the outer box on a vehicle, the outer box will be damaged by the impact, and the plastic container or glass substrate inside Accidents such as damage to photomask blanks, reticles, photomasks, etc. occur.
[0004]
As a countermeasure against the above problem, a packing form using a buffer member as shown in FIG. 7 is adopted. That is, when the plastic container 400 storing the glass substrate, photomask blanks, reticle, photomask, etc. is stored in the outer box 600, the container member 601 (made of corrugated cardboard) and the polystyrene foam are placed between the outer box 600 and the plastic container 400.
